is limited to values COMPLETE, ERROR. But the vast majority of the logging
invocations will be made DURING processing of a request, when it's neither
complete nor failed. What should be shown?
Michael: good question - limiting the enumeration was too restrictive - in the
call yesterday we added INPROGRESS based on feedback from Acumos and from Dave
on the spec page and Chris on the acumos page
In general we will try to sync the two spec pages onap/acumos - where the onap
page drives the common parts of the acumos spec
https://wiki.acumos.org/display/OAM/Log+Standards
https://wiki.onap.org/pages/?pageId=28378955
The larger logging/acumos logging team has been working with Portal - as of
today I will be looking to use their aspect advice class in portal/sdk as a
concrete RI in addition to our WIP aspect wrapper
https://git.onap.org/logging-analytics/tree/reference
https://git.onap.org/portal/sdk/tree/ecomp-sdk/epsdk-core/src/main/java/org/onap/portalsdk/core/logging
1. what to do about TargetElement, in Acumos we don't have virtual network
functions.
Michael: for targetElement - yes this is ONAP specific - this has come up a
couple times - I will add a column in the spec table for non-general/industry
logging MDC's (beyond the standard request/invocation ones for example) - the
same type off issue that occurs in spec/proprietary jpa/orm or cloud
native/agnostic artifacts in onap.
I expect we will have 2 categories (industry, native(ONAP/Acumos)
1. Can we get one example of log file output columns, with all the MDC's
value populated as it is generated in logs? Ex: value under RequestID,
InvocationID, InstanceUUID, ServiceName, etc..
Michael: We published some examples in the spec page table - there are
clickable MDC links on each line - some are missing - I will fix them.
https://wiki.onap.org/pages/viewpage.action?pageId=28378955#ONAPApplicationLoggingSpecificationv1.2(Casablanca)-MappedDiagnosticContextTable
Some of the older examples before we updated the spec need to be adjusted -
however the developer section has output of the logging library which is being
coded to implement/demo the spec
https://wiki.onap.org/display/DW/Logging+Developer+Guide
see example here
https://wiki.onap.org/display/DW/Logging+Developer+Guide#LoggingDeveloperGuide-UseCase:SingleRESTcall-withENTRY/EXITMarkersaroundin-methodlog
1. If we don't get RequestID from header of REST calls then do we need to
generate one? If so then what is the rule of generating random number?
Michael: Yes, the rule is pass-through or generate - there is an example in the
SLF4J library in
https://git.onap.org/logging-analytics/tree/reference/logging-slf4j/src/main/java/org/onap/logging/ref/slf4j/ONAPLogAdapter.java#n103
private static UUID sInstanceUUID = UUID.randomUUID();
Thank you
